CUSHION-TIRE FOR VEHICLES.

To all whom it may concern:

Be it known that I, JAMEs SEADLER, a citizen of the United States,residing at Sacramento, in the county of Sacramento and State ofCalifornia, have invented new and useful Improvements in Cushion-Tiresfor Vehicles, of which the following is a specification.

This invention relates to cushion tires for vehicles.

The main object of this invention is to provide a cushion tire whichshall be particularly adapted for use on heavy freighting trucks of themotor-driven type.

Another object of the invention is to construct a tire which consists ofindependent removable sections, adapted to be applied to the outerperiphery of an ordinary wheel; tires formed of independent resilientsections or blocks, together with a suitable interlocking means,producing a tire of the non-skidding type, which has considerableresiliency with unusual strength and durability.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed havingreference to the accompanying drawings, in which Figure 1 is a crosssection of the tire. Fig. 2 is a side elevation, partly broken away.Fig. 3 is a plan view, showing the interlocking ring and the position ofthe independent tread sections.

Referring to the drawings: A. indicates a portion of a wheel of theusual construction, around the outer periphery of which is secured theusual tire band 2, and surrounding same in concentric spaced relation isan interlocking ring 3, between which and the inner band 2 are placed asuitable number of independent elastic tread sections, generallyindicated at 4. The independent elastic tire sections here shown areprovided with base portions 5, adapted to set firmly between the innerand outer rings 2 and 3, and also provided with projecting treadportions 6, which project through perforations 7, formed in theinterlocking ring for this purpose. For the purpose of locking the treadsections against side movement, any suitable side plates may be applied,as indicated at 8 and 9, which are secured in position by bolts 10.

In operation, when it is desired to place the resilient tire section inposition on the Specification of Letters Patent.

Serial No. 757,293.

felly encircling band 2, it becomes necessary to place the treadprojections 6 in position in the opening 7, formed in the interlockingring, the side plate 9 being removed, it will then be possible to slidethe interlocking ring, together with the independent resilient sections,into position on the felly encircling band, and in some instances, whereit is desired to produce a considerable compression of the elastic baseportion 5 between the outer ancl inner rings 2 and 3, it. becomesnecessary to force shims, as 11, between the base portions 5 of theindependent elastic sections and the tire band 2. These shims mayconsist of a continuous annular ring, or may be formed in as manyindependent sections as may prove desir able. The side plates 8 and 9are then secured in position by the bolts 10, making the tire ready foruse. The interlocking ring 3 will thus form part of the running tread ofthe wheel, while the resilient projections 6, projecting through thesurface of the ring, will form an ideal anti-skid surface. It may alsobe seen that any section injured or too much worn may be easily replacedat any time by simply removing one or another of the side plates 8 or 9,and that any degree of resiliency between the outer and inner rings maybe secured by varying the elasticity of the composition, or byincreasing or decreasing the thickness of the shims 11.

The tire constructed as here shown is simple and compact in constructionand is particularly adapted for heavy freighting purposes in connectionwith motor-driven trucks and the like. The materials and finish of theseveral parts may be such as judgment and experience of the manufacturermay dictate.

I wish it understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims, and that I do not wish to limit myself to the specificdesign and construction here shown.

Having thus described my invention, what I claim and desire to secure byLet ters Patent is:

1. In a vehicle tire, the combination with the metallic tire and fellyof a wheel, of an interlocking tread ring spaced in concentric relationwith same, perforations formed in the interlocking tread ring, resilienthexagonal shaped block members interso i for securing the resilientblock members against side movement on the tire.

2. In a Vehicle tlre, the comblnatlon with m the metallic tire and tellyof a wheel, or" an nterlocking tread ring spaced 1n conce'n-.

tric relation with same, perforations formed 1n the' mterloclnngtreadring, lndependent reslllent members interposed between the 15 ringshaving knob-shaped extensions formed on their outer surface, projecting"through the perforations in the outer ring to form an antiskid' treadsurface; shims interposed between said resilient members and themetallic tire to vary the resiliency of said members and side platessecured to the opposite sides of the telly to prevent side movement ofthe resilient members.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
